The following table lists the metrics available for the Microsoft.Network/applicationgateways resource type.
Table headings
- Metric - The metric display name as it appears in the Azure portal.
- Name in Rest API - Metric name as referred to in the REST API.
- Advanced platform metrics - A premium, paid tier of platform metrics in Azure Monitor that provide more granular observability for Azure resources.
- Unit - Unit of measure.
- Aggregation - The default aggregation type. Valid values: Average, Minimum, Maximum, Total, Count.
- Dimensions - Dimensions available for the metric.
- Time Grains - Intervals at which the metric is sampled. For example,
PT1Mindicates that the metric is sampled every minute,PT30Mevery 30 minutes,PT1Hevery hour, and so on. - DS Export -S Whether the metric is exportable to Azure Monitor Logs via Diagnostic Settings.
For information on exporting metrics, see - Metrics export using data collection rules and Create diagnostic settings in Azure Monitor.
For information on metric retention, see Azure Monitor Metrics overview.
For a list of supported logs, see Supported log categories - Microsoft.Network/applicationgateways
| Metric | Name in REST API | Advanced platform metrics | Unit | Aggregation | Dimensions | Time Grains | DS Export |
|---|---|---|---|---|---|---|---|
| Application Gateway Total Time Time that it takes for a request to be processed and its response to be sent. This is the interval from the time when Application Gateway receives the first byte of an HTTP request to the time when the response send operation finishes. It's important to note that this usually includes the Application Gateway processing time, time that the request and response packets are traveling over the network and the time the backend server took to respond. |
